MySQL replication error 1146

Any idea why there is '1146 - table doesn't exists' on 'CREATE TABLE IF NOT EXISTS...' statement. It actually happened only on one of the slaves (there are two in total):

Last_SQL_Error: Error 'Table 'db_name.table_name' doesn't exist' on query. Default database: 'db_name'. Query: 'CREATE TABLE IF NOT EXISTS `table_name` (
          `step_id` int(11) NOT NULL,
          `item_id` int(11) NOT NULL,
          `item_type` varchar(128) COLLATE utf8_unicode_ci NOT NULL,
          `date_attached` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
          PRIMARY KEY (`step_id`,`item_id`,`item_type`)
        ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci'

EDIT:

I've re-synced this table but I'm not sure why this happened.

130802  9:32:03 [ERROR] Cannot find or open table db_name/table_name from
the internal data dictionary of InnoDB though the .frm file for the
table exists. Maybe you have deleted and recreated InnoDB data
files but have forgotten to delete the corresponding .frm files
of InnoDB tables, or you have moved .frm files to another database?
or, the table contains indexes that this version of the engine
doesn't support.
See http://dev.mysql.com/doc/refman/5.5/en/innodb-troubleshooting.html
how you can resolve the problem.
